title: Histopathological and lipid changes in experimental colon cancer: effect of coconut kernal (Cocos nucifera Linn.) and (Capsicum annum Linn.) red chilli powder.
abstract: Influence of coconut kernal and red chilli on the metabolism of lipids was studied in animals given 1,2-dimethylhydrazine (DMH). The average weight gain by the animals in the coconut kernal group was more than DMH and chilli treated groups. The concentration of cholesterol showed a decrease and phospholipids an increase in most of the tissues studied, of the kernal groups. The cholesterol-phospholipid ratio was found to be increased in most of the tissues of all experimental groups, when compared to control animals. HMG CoA reductase activity decreased in the high fat and most of the tissues of the kernal + DMH, kernal + chilli and kernal + chilli + DMH groups, while it increased in the DMH, chilli and chilli + DMH groups. Histopathological studies showed that coconut kernal supplemented animals had fewer papillae, lesser infiltration into the submucosa and lesser changes in the cytoplasm with decreased mitotic figures. Coconut kernal, thus reduced the mutagenic and carcinogenic effect of chilli and DMH respectively.
